Best 9mm Suppressors in 2020 – A Comprehensive Guide

Best 9mm Suppressors

The suppressor is an amazing accessory for the times when you don’t want to bother people at the range when using your 9mm pistol caliber carbines. Having a 9mm suppressor does more than just help you minimize the noise produced by the pistol, but it also helps to reduce recoil to make your weapon more manageable.

With less recoil, your shots will be more accurate for a more enjoyable time at the range. That now raises the question, what is the right suppressor? The best 9mm suppressor will depend on individual preference and there’s no easy answer for everyone there. In the meantime, we have shortlisted some of the best suppressors on the market out there in our article today that will fill about every conceivable niche while keeping a lid on your 9mm pistol.

What to Look for in Suppressors

Aside from noise suppression to comfortable hearing levels, here are a few other aspects to consider when looking for the best 9mm suppressors:

Material

Obviously, the material construction of a suppressor matters a lot as it will determine its overall build quality. Most of them are made out of some type of steel, either stainless or titanium. You may also find suppressors bolstered by durable polymers to reinforce the steel for added stability, increase noise reduction, or minimize heat transfer. It is always better to go for hardier and lighter materials however they tend to come with a price.

Recoil Reduction

Some of the best suppressors will also work to balance out the recoil of your weapon. However, you need to keep in mind that this is just a side advantage and not the focus of a suppressor. Hence, you shouldn’t expect it to work as a muzzle brake. Still, a suppressor can help to add a little bit of stability to your weapon.

Compatibility

Depending on the weapon you use, you need to make sure that your suppressor can fit your gun and is rated for the kind of shooting you plan on carrying out. This is because some suppressors are only designed to be used with certain pistols while others can work for both compact and full-sized handguns or even full-auto shooting.

Ease of Attachment

Certain suppressors can be screwed on the end of your gun easily while others might require a lengthier installation process. We would recommend focusing on a suppressor that can be removed or attached quickly especially if you like to swap between suppressed shots and regular fire frequently.

Weight

Lastly, you need to keep in mind the weight of the suppressor before purchasing. A light suppressor is always better since they won’t throw your aim off when attached to the barrel. While heavier suppressor is tougher, they tend to make your firearm more difficult to handle.

  • Material: Aluminum/stainless steel
  • Finish: Hardcoat Anodized
  • Attachment: 1/2×28 booster included. Compatible with GM-9 mounts

Modularity is slowly becoming a common feature among suppressors and why shouldn’t it be so? Everyone loves something that’s easy to use and versatile. This is what makes the configurability of Gemtech’s latest 9mm accessory a surprise to absolutely no one.

The Lunar 9 runs in two different lengths – 7 or 4.7 inches – both of which are extremely lightweight with a maximum of 10 ounces, making this a perfect all-rounder for tactical and pleasure shooting purposes.

On top of that, the Gemtech Lunar 9 is even compatible with GM-9 mounts thanks to the company’s Multi-Mount system that includes three-lug, and direct thread. Since it is a suppressor, it has the ability to knock your pistol’s noise down to the 120 dB range, shortened up to the mid-130s. Though you will still need to put on earplugs, this is still a comfortable level to work with.

2. Dead Air Wolf-9SD

Best Configurable 9mm Suppressors

Specifications

  • Caliber: 9mm/.300 Blackout
  • Weight: 14.7/7.5 ounces
  • Length: 7.58/4.1 inches
  • Diameter: 1.618 inches
  • Material: Stainless Steel
  • Finish: Cerakote
  • Attachment: ½-28 direct thread insert
  • Average Decibels: 123 dB full configuration

While this may not be the first pistol suppressor you’d reach for when you want to take your weapon through its paces, the Wolf-9SD is still one of the best choices for your sub-gun or carbine. The 1.618-inch diameter does a number on the sound reduction of your gun which is basically what the majority of the shooters look for in a suppressor anyway.

On top of that, the dead Air Wolf even comes with a fairly distinctive design for a fully welded suppressor. You get the option to unscrew at its midpoint to get a pint-sized configuration. The full-sized 9mm suppressor measures at 7.58 inches while the compact is at 4.1 inches.

Though the cut-down size would work on a pistol, owners might encounter a slight issue with its diameter. Plus the Wolf is pretty hefty at 14 and 7 ounces weight for both configurations respectively. Nonetheless, if you’re mainly planning on running sub or carbines, then this will definitely work for your sidearm in a pinch.

3. CGS MOD-9

The suppressor is made with Aluminum as the main ingredient including the suppressor’s 6 baffle stack and tube to keep it a light 10-ounce weight.

CGS has successfully cooked up a pretty quiet suppressor – almost mouse-sneeze quiet. However, the noise level will obviously depend on the ammo and barrel length. Most 9mms with a 4-inch-plus fire tube can expect to generate noise levels between 113 and 120 dB with the MOD-9 mounted on. One last thing worth mentioning is that the MOD-9 suppressor offers an impressive piston assembly with a 12-point rotational adjustment to dial in for impact shift.
